"Demand for SIP trunking will continue to flourish in the United States, driven by the weak economy and enterprise customers' desire to reduce their telephony costs. At the same time, service providers will continue to expand and enhance their VoIP capabilities with advanced applications such as unified communications and functionality like mobility in an effort to drive further adoption of SIP trunking. However, the market will remain fragmented with many players vying for a seat at the table, making consolidation a likely scenario in the next 18 months as service providers strive to scale their VoIP solutions, differentiate their SIP trunking service from competitors, and deliver the best customer experience possible." - Amy Lind, research manager, Enterprise Voice and IP Communications Services
